Product Description

SG10 type H grade insulation dry type transformer

Product description

Class H insulation

The dry transformer has following insulation classes: class B, class F, class H, class C, etc. their thermal-endurance temperature is respectively 130 ºC, 150 ºC, 180ºC, and 220ºC. As adopting new material and new technology of deport, the model SG(B) dry type transformer has reached class H of thermal endurance, and some of its key location reached class C of thermal endurance.

Safety

Model SG(B) new products are dry transformer with the highest safety in current market. all of this insulating materials are of non-combustion supporting, self-extinguishing, nontoxic one. It shows advantages especially when used in those fields where high safety is required, humidity and temperature are high, and ventilation is poor, such as in power sites, underground railways, ships, chemical and metallurgical sites. Outer casing and blower fan can be provided if required by users.

Reliability

The coil of model SG(B) is specially designed and made of special material with special technical process, which renders the product excellent moisture-proof, mildew-proof and salty fog-proof performances, much higher temperature endurance, and permanent chap free ability. The nomex based insulating system can remains at the extraordinary excellent and mechanical performances and compressive strength, therefore its coil can keep a compact and tight structure after many years service and the transformer can withstand short circuit voltage.

Environmental protection

Model SG(B) product can be disassembled for recovery after life end, thus meeting clients requirements one environmental protection. While those dry transformers made via epoxy cast can't be disassembled, because the resin glass has cured into an integral one, and therefore is unfavorable for environmental protection.

Strong overload capacity

Model SG(B) adopts new structure, novel material and up to date technology, featuring good heat-sinking capability, long thermal endurance, strong overload capability, it can run stably under 120% rated load for a long period. It can keep a long term running under full load in IP23 environment without forced air ventilation necessary.
